Question 1

Consider the following conditions and select the correct option:
1) Fluid is real
2) Steady flow
3) Fluid should follow Newton’s law
4) Pressure is constant on fluid
5) Flow is incompressible
Which of the conditions does Bernoulli equation follows?

Question 2

Consider the following statements related to a horizontal venturimeter.
I. The velocity of flow in the main pipe is greater and the pressure is lesser than that at throat section.
II. The velocity of flow in the main pipe is lower and the pressure is larger than that at the throat section.
III. The upstream pressure difference between the main pipe and throat section is positive.
IV. The upstream pressure difference between the main pipe and throat section is negative.
Which of the above statements are INCORRECT?

Question 3

If the coefficient of discharge of a venturimeter is 0.96, the venturi constant is 0.4m2.5/s and venturi head is 0.15m, then the discharge through the venturimeter is (l/s)?

Question 4

Consider a flow section in which there are two points A & B. Point A is 4.5 m above the datum , velocity is 6m/s and pressure is atmospheric. Point B is 3m above datum and a pump is installed at B delivers a pressure head of 1m. What is the velocity (m/s) at B such that head loss is occur of 1m at B?(taking g=10m/s^2 and ρ =1000kg/m^3)

Question 5

Water flows steadily through the tanks as shown in figure below :

The height hA is ____ m [considering that depth of water in tanks A and B do not change with time]

Question 6

A pitot tube with coefficient of 0.98 is used to measure the velocity of water in a pipe. If the head difference of U tube holding mercury (of relative density 13.6) is 12cm.What is the velocity of water(m/s)?(Take g =10m/s2)
